® assuredcommunications™ RF-387-AT002 VHF VEHICULAR WHIP ANTENNA 30-108 MHz with GPS antenna The Harris RF-387-AT002 vehicular center-fed whip antenna is designed for use with the RF-5800V transceiver. It provides both a low-band VHF antenna and GPS antenna integrated within one package. The 121-inch whip provides exceptional gain and instantaneous bandwidth performance over the whip length without unsightly bulges. This puts the power pattern on the horizon allowing exceptional LOS communications without the need for a ground plane. The VHF center-fed element and matching network is rated for 100 Watts. The flexible spring feed-through mounting base contains a GPS antenna, required with the RF-5800V-MP when equipped with the internal GPS option. With the GPS spring base, the overall antenna length is 131 inches. On the underside of the base, there is a ground stud and two connectors: the VHF connector is a female BNC and the GPS connector is a female SMA. Its feed through spring base mounts directly to a Harris RF-292 Universal Antenna Mount or to any horizontal surface using four 0.4 inch holes spaced 90 degrees on a 4.5 inch bolt bole circle with a 3.5 inch center cut-out.
